Abstract：

In order to cleanly use lignite in large-scale,the status of fragmentation during thermal conversion of coal at home and abroad was analyzed.The fragmentation mechanism,the effects of coal quality and transformation conditions on fragmentation of coal were investigated.Due to the issue such as high content of dust in tar during the utilization of low rank coal,some solutions for inhibit pathway of thermal fragmentation were proposed.The fragmentation mechanism could be revealed by analyzing and regulating the physical and chemical properties of low rank coal and the transformation conditions.Based on the thermal reaction products,the relationship between fragmentation and heating process was established. The amount of dust could be decreased through exploiting new reactor which minimized the motion of coal particles.A technology approach for clean and efficient utilization of low rank coal was built.
